Abstract

The crystal structures of the title compounds are determined by Rietveld refinement of powder XRD data. All the compounds crystallize in the 6H-BaTiO3 type structure (hexagonal, space group P63/mmc). Magnetic susceptibility measurements reveal that the effective magnetic moments are smaller than values estimated using spin-only moments, indicating the presence of spin-orbit coupling and strong interactions in the [(Ru0.5Ir0.5)2O9] face-shared double-octahedra that contain a disordered mixture of Ru and Ir on a single crystallographic site. Magnetic anomalies are observed for the compounds Ba3PrRuIrO9, Ba3TbRuIrO9, and Ba3NdRuIrO9 at 3.5, 13, and 8 K, respectively.
